SeriousSeverity: Serious - have it checked soon
Engine Oil Pressure Sensor/Switch Circuit Low Voltage
Key terms: SAE J2012: the standard generic code list · Powertrain: engine, transmission and emissions
1What it means in plain English
The oil pressure sensor signal is lower than the range the engine computer considers possible, so it cannot trust the oil pressure reading.
2Common causes
- Faulty oil pressure sensor
- Low engine oil level
- Damaged wiring or connector (short to ground)
- Wrong oil viscosity or a blocked oil filter
- Genuine low oil pressure from a worn engine or failing oil pump
3Can I drive?
Do not rely on the oil-pressure reading. Stop the engine as soon as it is safe and have the car diagnosed before driving further: if oil pressure really is low, continuing can destroy the engine.
This page gives general information. It is not professional advice. For a definite diagnosis and a repair quote, ask a qualified mechanic to inspect the car.
